The encapsulation of the viral RNA condensate inside the capsid is a crucial step in the late stages of the HIV-1 replication cycle. While it is agreed that RNA encapsulation depends on RNA-bound integrase (IN), that capsid-bound IN-RNA filaments are present within the capsid, and that the ribonucleoprotein (RNP) compl...

It is shown that bacterial RNA polymerase faithfully transcribes an eight-letter genetic alphabet and recognises unnatural base pairs through mechanisms similar to those used for natural DNA.

The structure of such a polymerase ribozyme bound to RNA substrates comprising the template, primer, and nucleoside triphosphate (NTP) analog is presented, revealing how directed evolution shaped flanking elements around a highly conserved catalytic core derived from the ancestral class I ligase ribozyme.
